In our previous paper, the results of a survey on proposed design standards for graphics used for distributed control systems (DCSs) in plant operation were reported and a set of design standards was proposed. In this paper, the proposed design standards are reinforced and thoroughly explained. Next, a survey of operators was conducted to prove that the design standards are acceptable to plant operators. Several practical ideas for designing graphics for plant operation in order to show differences from normal states, alarm information and non-steady-state operations are also proposed. Furthermore, some recommendations for implementing and maintaining the graphics are explained. These standards and ideas will help engineers provide effective graphics and enhance operational efficiency.
